X-ray images of Tycho’s supernova remnant (Tycho’s SNR) show a pattern of bright clumps and fainter holes. By comparing new data from NASA’s Chandra...
A new video released by NASA’s Chandra mission shows how Cassiopeia A has evolved over more than a dozen years in X-ray light.
Cassiopeia A, which is...
Astronomers have announced the discovery of the most massive star ever known to be destroyed by a supernova explosion. Dubbed SN 2016iet, the explosive...
A team of researchers from Germany, Austria and Australia has found traces of the radioactive isotope iron-60 — the tell-tale signature of a supernova...
Astronomers have used NASA’s Transiting Exoplanet Survey Satellite (TESS) to see what was happening around the supernova ASASSN-18tb in the first moments...
The NASA/ESA Hubble Space Telescope has produced a spectacularly detailed image of a spiral galaxy called NGC 4051.
This Hubble image shows the intermediate...
Astronomers using the 8-m Subaru Telescope have identified 1,824 new supernova candidates, including 58 Type Ia supernovae over 8 billion light-years away.
Supernovae...
Between 8 and 2 million years ago, cosmic-ray energy from one or more nearby supernovae reached Earth and pummeled the planet’s atmosphere, initiating...
A team of astronomers from MIT has observed evidence that the Universe’s first stars exploded as asymmetric supernovae, strong enough to scatter heavy...
Astronomers using the Magellan telescopes at Las Campanas Observatory, Chile, have detected the faint signal emitted by hydrogen gas in the remnant of...
Approximately 2.6 million years ago (Pliocene epoch), a tsunami of cosmic energy from a massive supernova or a series of them about 150 light-years away...
These threads of red snaking amidst dark, turbulent clouds make up a cosmic object known as SNR 0454-67.2. This tangled web is actually the remnants from...
Two teams of astronomers have finally found the long-sought progenitor star to a Type Ic supernova by sifting through Hubble archival data.
An artist’s...
A team of astronomers has observed a new phenomenon in the aftermath of SN 2012au, an extremely energetic supernova discovered on March 14, 2012 in the...
By observing two neighboring galaxies, the Large Magellanic Cloud and the Small Magellanic Cloud, using the Murchison Widefield Array radio telescope in...
Conditions favorable for gravitational wave-emitting mergers of massive black holes exist in the outer gas disks of big spiral galaxies, according to a...
The NASA/ESA Hubble Space Telescope has taken a picture of a little known galaxy called UGC 12682.
This Hubble image shows the irregular galaxy UGC 12682....
The detection of a radial magnetic field across the inner ring of SNR 1987A, the remnant of a supernova first witnessed three decades ago, provides insight...
